Title: Improvements in or relating to a control assembly for a web feeding apparatus
Inventor: COOKSEY OTHA
IPC: B41F33/18
Filed: 1951-05-08
Abstract: 712,316. Feeding and cutting webs in printing machines. KORIATH, E. G., THIELE, H. F., and KORTHE ENGINEERING CO. May 8, 1951, No. 10775/51. Classes 100 (1) and 100 (2) A control assembly for use with a travelling web on a printing press comprises control elements consisting of two electric switch elements 13, 14 operated by adjustable cams mounted on a rotatable shaft 21 on which is fixed an arm 32 provided with a feeler 33 which contacts the web W. The switch 14 is closed when the web tears or breaks and the switch 13 is closed when the feeler is raised clear of the web and held by the engagement of an extension 25 of the shaft which engages the end of a bracket 18. The switch 14 operates means to sever and clamp the web comprising a base bar 37 provided with a strap 38 having a smooth edge and a strap provided with a serrated edge mounted on opposite sides thereof. A moving bar 47 is connected to the bar 37 by links 44, 45 and is held away from the bar 37 by a latch 54 operated by a solenoid 63 which moves the latch 54, a spring 52 causing the bars to close and sever the web and clamp the approaching edge of the web between the bars 47, 37. To ensure that the severed portion of the web is cleared from the machine a guide roller 76 having considerable inertia is disposed adjacent to the severing and clamping means and is driven by movement of the web. Rollers 84 are mounted on cams 81 fixed to a rotatable shaft 77 on which is mounted a lever 85 held in position by a latch operated by a solenoid which is energized when the web breaks to release the lever to cause the rollers 84 to press the web into firm contact with the roller 76 and feed it outside the processing unit. Alternatively compressed air may be used to force the web into contact with the rollers 76. Several control elements are mounted on the press together with the severing and clamping means and the switches and solenoids may be so connected with a relay that a break in the web will stop the machine. When threading a web into the machine the control elements are held away from the web, closing switches 13 which are arranged in a circuit so that the machine cannot be run at full speed until all the feelers of the control elements are placed in contact with the web.

Title: Hydration of olefins in the presence of a solvent
Inventor: HENKE ALFRED MATHIAS
IPC: B01J27/02
Filed: 1962-03-21
Abstract: Olefines containing 3 or more carbon atoms are hydrated with water over a solid hydration catalyst at a temperature in the range 175-600 DEG F. to form an alcohol, at least part of the olefin and part of the water being in the liquid state, and the reaction taking place in the presence of an organic solvent (other than the product alcohol) which is a liquid miscible with the reactants to form solutions in which the product alcohol is more soluble than in the reactants or solvent per se so that the mixture forms two solvent-containing phases one containing water and the other olefine, and both containing the product alcohol and being insoluble in each other. Suitable solvents are, for example, methyl, ethyl, n-propyl, iso-propyl, and tertiary butyl alcohols, methyl ethyl ether, dioxane, ethylene glycol monomethyl ether, acetone or acetic acid.  If desired an olefine which hydrates to form a solvent alcohol at a faster rate than the olefine starting material may be added to the reaction mixture.  Suitable catalysts are, for example, blue oxide of tungsten, tungsten sulphide, nickel sulphide, ion exchange resins, alumina, thoria, zirconia, aluminium sulphate, kaolin and titania. The process may be carried out batchwise or continuously.  In examples (a) methyl butenes are converted to tertiary amyl alcohol using acetic acid as solvent and (b) isobutylene to tertiary butyl alcohol using isopropanol as solvent.

Patent GB-391306-A (GB)
Title: Process for the separation of stearin and olein from mixtures thereof
IPC: C11C1/00
Filed: 1932-04-15
Abstract: Mixtures of fatty acids are resolved into olein and stearin by dissolving in oxygen-free solvents, incorporating water as a colloidal solution or emulsion, cooling to crystallize the solid acids, and filtering or otherwise separating.  Solvents specified are benzine, benzene, toluene, chlorinated hydrocarbons, and mixtures thereof.  The water may be added as water-diluted alcohols, ketones, aldehydes, or other substances dissolving wholly or partially in water and in the solvent or the fatty acids, or/and as a solution of an emulsifying agent.  Emulsifying agents specified are sulphonated organic acids, sulphonated alcohols, sulphonated ketones, their salts and esters, and salts of fatty acids; the fatty acid salts are formed by stirring in aqueous solutions or suspensions of nitrogenous waxes, oxides, hydrates, or carbonates, of metals, unless the fatty acids already contain soap or other emulsifying agent.  In examples: (1) 1000 kg. of melted Twitchelled bone fatty acids are dissolved in a jacketed vessel in 700 kg. of petroleum spirit, B.P. 105-175 DEG  C., 50-70 kg. of 75 per cent methyl alcohol are stirred in at 35 DEG  C., stirring continued until the temperature falls to 10-12 DEG  C., and the crystalline pulp is filter-pressed.  The stearin cakes are melted, the separated dilute alcohol removed, and residual alcohol removed by distillation to 90 DEG  C.; the solvent is driven off by steam.  Stearin of higher M.P. and lower iodine number may be obtained by first stirring the cakes from the filter press with 700 kg. of solvent at 10-12 DEG  C., and filter-pressing; the filtrate is used to treat a fresh charge.  The filtrate solution of olein from the first pressing is cooled to 3 DEG  C. to separate residual stearin, and freed from methyl alcohol and solvent, leaving olein of M.P. 10-11 DEG  C., which may be further cooled and filtered.  (2) 1000 kg. of Twitchelled bone fatty acids are emulsified by reaction with 30 litres of 25 per cent ammonia solution, stirred at 35 DEG  C. with 800 litres of benzine B.P. 100-125 DEG  C., cooled with stirring to 10-12 DEG  C., and filter-pressed.  Specification 156,259, [Class 91, Oils &c.], is referred to.

Abstract: Substantially spherical hollow particles of synthetic thermoplastic polymer are made by first charging a polymerization reactor with deionized water, then adding colloidal silica, an aqueous solution of a diethanolamine/adipic acid copolymer and potassium dichromate.  The pH is then adjusted to 4 with hydrochloric acid. An oil-phase mixture comprising methyl methacrylate, neopentane and benzoyl peroxide is then added with violent agitation.  The mixture is held at 80 DEG  C. for 24 hours, then filtered and the polymer particles dried at 30 DEG C.  They are then heated at 150 DEG  C., when they expand to hollow microspheres. The above process can similarly be used with comonomers for the methyl methacrylate, viz. ethyl methacrylate, butyl acrylate, acrylonitrile, vinyl acetate, styrene, o-chlorostyrene and p-t-butylstyrene; and similarly for the production of poly-o-chlorostyrene, polyvinylbenzyl chloride, and acrylonitrile/vinylidene chloride, styrene/methacrylic acid and styrene/methacrylic acid/vinyl benzyl chloride copolymers.ALSO:Paper comprises a web of fibres having enmeshed therein substantially spherical hollow particles of thermoplastic synthetic polymer.  It may be made by deposition upon a screen from a slurry of the fibres and hollow particles.  The hollow particles may be of polymethyl methacrylate, or of copolymers of methyl methacrylate with styrene, ethyl methacrylate, orthochloro-styrene, acrylonitrile, para-tertiarybutylstyrene, vinyl acetate or butyl acrylate or of polyorthochlorostyrene, or polyvinylbenzyl chloride, or of a copolymer of acrylonitrile and vinylidene chloride, a copolymer of styrene and methacrylic acid or a terpolymer of these two and vinylbenzyl chloride.  A cationic starch, retention aid or alum may also be present in the slurry.  The product has good opacity and low density, and can readily be embossed at a temperature about or above the softening temperature of the polymer.

Record cards are fed through a statistical machine or the like by a reciprocating gripper carriage having two sets of grippers for successively engaging the cards and a stationary gripper holding each card between the periods it is engaged by the two moving sets. The cards are fed from hopper 2, Fig. 3, by the usual picker 3 actuated by a cam-operated lever 6. The gripper carriage 5 is also connected to a cam-operated lever and carries gripper pairs 4 and 14 having rubber-coated surfaces for engaging the cards. The picker forwards a card to the grippers 4 when the carriage is in the right-hand position (Fig. 3) and the carriage is then moved towards the left with a step-by-step motion so that the card moves line by line past the first sensing station 11. At the end of this movement the card is held by the stationary gripper 12; grippers 4 release it and are carried back to the right hand position to receive the next card. This movement brings the second pair of grippers into engagement with the first card, as shown in Fig. 3, and the subsequent movement feeds both cards step-by-step past the corresponding sensing stations 11 and 13. In first sensing station certain control data may be read off and in the second, numerical data. In the extreme left-hand position of the carriage, Fig. 5, the leading card may be directed by a deflector into a gripper on the periphery of stacking drum 16 to be carried thereby to a stacker (not shown). Otherwise the deflector may be set to pass the card in direction of arrow 20 to further equipment. At each step in the feedmotion sensing pins are raised in the sensing stations 11, 13 to control contacts according as to whether the card has a hole or not in each position.
